Transducer Mounting & Trolling Motor Power Questions

[TheChad]

Hey all,

I just purchased a Lowrance LCX-26C HD Fish Finder/GPS for my 17' Lowe Fish & Ski.

Currently I have a Humminbird 727 installed on the Help, and I am going to be replacing that with eh LCX-26c HD, and moving the 727 Up to the bow.

I assume that the holes used to mount the Humminbird transucer on the transom, probably wont line up with the mounting holes for the Lowrance transducer?

If that is the case, What do you guys suggest to do with the holes from the Hummin bird transducer?

As for the 727 that I am relocating to the bow, What is the suggested hook up for power? Should I tap into the 24v trolling motor outlet in the bow, or should I run the power wires back to the help where they are connected now on 12v? (I assume the 727 is capable of running on the 24v system, anyone know?)


Trolling Motor Question(s):

Right now I have a 71lb Digital Motor Guide 50" shaft. I have many complaints about this motor, but that I'll save for another time.

I am looking at getting a Minn Kota PowerDrive motor to replace it. Minn kota offers a 70lb w/Universal Sonar, and a 55lb w/universal Sonar.

The 71lb that i have now, is alot. If i turn it all the way up, the boat gets moving at a pretty good speed. I was just going to get the 65lb, but Minn Kota doesn't offer the 65lb w/Universal Sonar, So that would drop me all the way down to 55lb, which is also 12v.

What is your guy's input on this? will a 55lb 12v motor be enough? Since I already have the 2 batterties, I would just rewire them in series if I did downgread to the 55lb 12v motor.

Also, The 50" shaft that I have now is too short, any little wake, and the blades start comming out of the water. The fishing package from the factory comes with a 60" shaft, but the Tracker Targa 175 Sport, which is a very similar boat, comes with a 54" shaft.

Do I need a 60" or a 54"? This is a Deep Vee hull. That too could make the choice on 55lb vs 70lb because the 55lb only comes in a 54", the 70lb I can get in 54" or 60"

Thanks for the help.

Re: Transducer Mounting & Trolling Motor Power Questions

Your new Lowrance will not work on 24V. Needs 12V. As for the trolling motor, I would go with the 70 lb. A 24V system uses less current than a comparable 12V one. If you ever need that extra power to get you out of trouble, you'll have it. I would also go with the 60" shaft to be sure the prop stays in the water when it gets rough. 2 batteries wired in series gives you 24V, parallel will give you 12V. Also keep in mine the built in transducer only has a 12 degree cone and will not give you temp readings. Other than that they work great. I would also get the auto pilot if you can. They are the greatest thing since sliced bread.

Yeah, The Lowrance will be mounted on the helm, and wired to the starting battery, which is 12v. The Humminbird 727 is the unit that I was interested in wireing to 24v as it will be mounted to the bow next to the trolling motor, which is 24v.

2 batteries wired in series gives you 24V, parallel will give you 12V.

Yeah, I ment for 12v I would wire the 2 batteries in parallel. I just mis-typed.

Also keep in mine the built in transducer only has a 12 degree cone and will not give you temp readings. Other than that they work great. I would also get the auto pilot if you can. They are the greatest thing since sliced bread.

12 degree cone is kind of dumb, especially since when using the trolling motor most are going to be in only a few feet of water..

That's good to hear about the Auto Pilot, I thought it sounded like a good idea, but wasn't sure how well it worked, So I'm glad to hear it works good.
